2.0
2.1
The PIC12F635/PIC16F636/639 devices have a 13-bit
program counter capable of addressing an 8K x 14
program memory space. Only the first 1K x 14
(0000h-03FFh, for the PIC12F635) and 2K x 14
(0000h-07FFh, for the PIC16F636/639) is physically
implemented. Accessing a location above these
boundaries will cause a wrap around within the first
2K x 14 space. The Reset vector is at 0000h and the
interrupt vector is at 0004h (see Figure 2-1).
2.2
The data memory (see Figure 2-2) is partitioned into
two banks, which contain the General Purpose
Registers (GPR) and the Special Function Registers
(SFR). The Special Function Registers are located in
the first 32 locations of each bank. Register locations
20h-7Fh in Bank 0 and A0h-BFh in Bank 1 are GPRs,
implemented as static RAM for the PIC16F636/639.
For the PIC12F635, register locations 40h through 7Fh
are GPRs implemented as static RAM. Register
locations F0h-FFh in Bank 1 point to addresses 70h-
7Fh in Bank 0. All other RAM is unimplemented and
returns ‘0’ when read. RP0 (STATUS<5>) is the bank
select bit.
